fix(wire): retarget stale /vql/execute callers + fuzz target to VCL

Completes the endpoint hard-rename (stage 1/5) for the callers it missed.
After the rust core route /vql/execute -> /vcl/execute (no alias), these
still pointed at the removed path:

- ffi/zig GraphQL gateway: full VQL->VCL sweep — outbound call to the rust
  core (graphql.zig), the gateway's own inbound /vcl/execute route
  (router.zig), and its GraphQL surface (executeVql -> executeVcl,
  VqlResult -> VclResult). The API-surface rename is a deliberate breaking
  change, consistent with the hard-rename applied everywhere else.
- examples/load-sample-data.sh, examples/smoke-test.sh: curl endpoint only.
- .clusterfuzzlite/build.sh: fuzz_vql_parser -> fuzz_vcl_parser (both
  fuzz/Cargo.toml and rust-core/fuzz/Cargo.toml already use fuzz_vcl_parser).

Deferred (different rename axis): examples/vql-queries/ dir, *.vql fixtures,
and "VQL" comments/seed-data prose -> tracked with the *.vql fixture-naming
stage.

No Zig toolchain here; verified statically (length-preserving token swaps,
zero residual vql in scope, no dangling executeVql/VqlResult references).
